Abstract
Description
Die Erfindung betrifft einen Zirkel für den Gebrauch an großflächigen Tafeln aus magnetischem Material, der an einem seiner beiden Schenkel einen Fuß trägt, mit dem er auf die Tafel gesetzt wird, wobei der Fuß mindestens einen Magneten trägt, der den Fuß mit seiner magnetischen Kraft an der Tafel hält.The The invention relates to a compass for use on large-area panels made of magnetic material that carries a foot on one of its two legs which he is placed on the board, with the foot at least one magnet wearing, the foot with holding his magnetic power at the blackboard.
Ein
Zirkel mit einem derartigen Fuß wurde
im Jahr 1998 von der Firma Pythago Color GmbH entwickelt und auf
den Markt gebracht. Dieser Zirkel ist in der
Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, einen leise auf Tafeln aufsetzbaren Zirkel zu schaffen, der auch bei oftmaligem Gebrauch die Tafeloberfläche nicht beschädigt, dem Fuß aber trotzdem einem sicheren Halt an der Tafel gibt.The Invention avoids the disadvantages of the prior art. It is the object of the invention, a silently placed on boards compass to create, even with frequent use, the board surface is not damaged, but the foot Nevertheless, there is a secure hold on the board.
Die Erfindung besteht darin, dass der Magnet zumindest auf der Fläche, mit der er auf der Tafel steht, einen dünnen Überzug aus einem weicheren Material trägt.The Invention is that the magnet at least on the surface, with he stands on the board, a thin cover of a softer material wearing.
Dieser Überzug über die Standfläche des Magneten verhindert die Geräuschbildung beim Aufsetzen des Magneten auf die Tafel, schont aber auch gleichzeitig die Tafeloberfläche vor mechanischen Beschädigungen.This cover over the footprint the magnet prevents the noise when putting the magnet on the board, but also protects at the same time the blackboard surface against mechanical damage.
Bei diesem Zirkel ist es bekannt, dass der Fuß dreiarmig ist und jeder seiner Arme an seinem Ende einen Magneten trägt. In diesem Fall wird jeder der Magnete an den drei Armen mit einem dünnen Überzug aus weichem Material versehen.at In this circle it is known that the foot is three - armed and each one of its Arms carrying a magnet at its end. In this case, each of the Magnets on the three arms with a thin cover of soft material Mistake.
Der Überzug kann eine aufgeklebte Folie sein, dauerhaft haltbarer ist es jedoch, wenn der Überzug aus einem napfartigen elastischen Körper besteht, der an seinem Rand eine Verdickung aufweist.The coating can a glued-on film, but it is permanently more durable, if the coating consists of a cup - like elastic body, which at his Edge has a thickening.
Hierbei ist es zweckmäßig, dass der Magnet an seinen Seitenflächen eine Nut hat, in die die Randverdickung des napfartigen elastischen Körpers einfällt. So ist ein dauerhaft fester Sitz gewährleistet.in this connection it is appropriate that the magnet on its side surfaces has a groove into which the edge thickening of the cup-like elastic Body invades. So is a permanently tight seat guaranteed.
Der dünne Überzug kann auch aus einem Napf aus tiefgezogener Folie bestehen, der auf den Magneten aufgeklebt ist.Of the thin coating can also consist of a cup of thermoformed foil, which is on the magnet is glued on.
Auch ist es möglich, dass der dünne Überzug aus einer Folie besteht, die im Tauchverfahren über jeden Magneten gezogen ist. Das erfolgt dadurch, dass die einzelnen Magneten an Zapfen eines Trägers magnetisch angekoppelt werden, der die Magneten durch ein Bad eines verflüssigten Überzuges führt, wonach der flüssige Überzug getrocknet wird und die überzogenen Magnete von den Zapfen abgenommen werden. Die Zapfen haben dabei einen geringeren Querschnitt als die zu überziehenden Magnete.Also Is it possible, that thin coating off a film that is drawn by dipping on each magnet is. This is done by the individual magnets on pins a carrier Magnetically coupled, the magnets through a bath of a liquefied coating leads, after which dried the liquid coating will and the plated Magnets are removed from the pins. The cones have it a smaller cross section than the magnets to be coated.
Es ist aber auch möglich, dass der Folienüberzug sich über den ganzen Fuß, zumindest aber über die Arme des Fußes erstreckt.It but it is also possible that the film cover over the whole foot, but at least over the arms of the foot extends.
Das Wesen der Erfindung ist nachstehend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The Essence of the invention is described below with reference to a in the drawing schematically illustrated embodiment explained in more detail. Show it:
